Abstract

1304956 2,2 - Dimethyl - 1,3 - propanediol monohydroxy pivalic ester BADISCHE ANILIN- & SODA-FABRIK AG 25 June 1970 [26 June 1939] 30826/70 Heading C2C 2,2 - Dimethyl - 1,3 - propanediol monohydroxypivalic ester is purified by distilling the crude at a temperature of above 100‹ C., with sulphuric or sulphonic acid. The distillation may be continuous with from 0À05 to 5% molar proportion of the acid.
